|SUV Rollovers: Center of Gravity - NASA/Goddard Space Flight Center Conceptual Image Lab|
Center of Gravity--Why Rollovers Happen (animation) - A particular object's center of gravity--in this case an SUV--will always be contained within the geometric confines of that vehicle as it's oriented in space relative to the pull of gravity. If there's a change in a vehicle's spatial orientation due to the imposition of some external force, the vehicle's center of gravity will shift from its original position as long as that external force persists...

|A CME Generates Reconnection in Earth's Magnetic Field - NASA/Goddard Space Flight Center Conceptual Image Lab|
A burst of fast material from the Sun generates magnetic reconnection events in the Earth's magnetic field. This eventually sends high-speed electrons and protons into the Earth's upper atmosphere to form aurora. Note: View the impact of a coronal mass ejection against the Earth's magnetic field. Animator: Walt Feimer (HTSI). Platforms/Sensors/Data Sets: 3D Unstructured-mesh Magnetosphere Simulation.

|Sensor Web: Smart Satellites - NASA/Goddard Space Flight Center Conceptual Image Lab|
Smart Satellites Get a Closer Look - Along with semi-autonomous advancements in the RapidFire system, NASA is testing new integration techniques with the EO-1 spacecraft and its cutting edge ALI instrument. It works like this: when MODIS spots an area on the ground that may indicate fire, advanced software puts out an alert. That message essentially instructs ALI to point itself towards the zone of interest and get a close-up...
